<p>Some schools have significantly lower percentage of applicants that report rank versus other schools. And you would not say a sample is representative unless it were random. You can’t make a statistical argument, for example, claiming that the mid-point SAT score reported by a “no-SAT-required” college (perhaps only 50% provide SAT scores) is therefore representative of the midpoint SAT score of all those that enrolled (this may be the case but you could not make the argument statisically with these data points). </p>
<p>Anyway, as I stated previously, its just my opinion. If you believe in the validity of the underlying data and the results from this formula seem reasonable to you, then you can feel comfortable relying on the list as an accurate assessment, and can use as you please.</p>
